What is a chromosome?

A chromosome is a threadlike strand of DNA in the cell nucleus that carries the genes in a linear order. It is also known as tightly wound DNA. It is a structure that DNA wraps around. MORE INFORMATION: A chromosome is an organized structure of DNA and protein that is found in cells. It is ( Full Answer )

What is chromosome?

A chromosome is an 'X' shaped gene which contains DNA, found inside living cells. Chromosomes are easily seen using a microscope and are normally invisible most of the time (this period of time called 'interphase') but become visible when the cell starts to multiply.

What is chromosomes?

The small bodies in the nucleus of a cell that carry the chemical"instructions" for reproduction of the cell. They consist ofstrands of DNA wrapped in a helix around a core of proteinChromosomes are thread-like structures that are found in thenucleus of a cell.

What are chromosomes?

Basically is genetic info. Different organisms have different types of chromosomes. In bacteria (prokaryotic cells) a chromosome consists of a loop of DNA; it has no end. Along the length of the DNA are segments called genes, which contain information that the cell uses for growth and devel ( Full Answer )

What do chromosomes do?

They carry the tens of thousands of traits that are inside you to make you look like who you are. During sexual reproduction your Parents give you half of each of their Genome; which are copies of theirs. Some of the traits may be dominant, which shows [are expressed] over the recessive traits ( Full Answer )

What does a Chromosome do?

\n. A chromosome makes you who you are. \n\nIn a cell, the chromosomes are located in the nucleus, the 'brain' of the cell. they are like the DNA, but not specifically. there is actual DNA for that. in a cell, the chromosomes are located in the nucleus, the 'brain' of the cell. they are like the D ( Full Answer )

What is an chromosome?

Chromosomes are rod-shaped structures usually found in pairs in the nucleus of a cell. They contain information determining characteristics of an organism when it is reproduced.

Where are the chromosomes?

Chromosomes are the rod-shaped, filamentous bodies present in the nucleus, which become visible during cell division. They are the carriers of the gene or unit of heredity. Chromosome are not visible in active nucleus due to their high water content, but are clearly seen during cell division.

Why do eukaryotic chromosomes have multiple origins of replication?

The eukaryotic genome is so much larger than the prokaryotic genomethat it would not be practical to rely on a single origin ofreplication site when copying it for cell division. Byincorporating several, the eukaryotic cell can divide withoutunnecessarily long delay in chromosomal replication.

Where are chromosomes?

Chromosomes are the rod-shaped, filamentous bodies present in the nucleus, which become visible during cell division. They are the carriers of the gene or unit of heredity. Chromosome are not visible in active nucleus due to their high water content, but are clearly seen during cell division..

What is the chromosomes?

Chromosomes are structures composed of DNA and proteins. They carry the genetic information of the cell. In eukaryotic cells they are located in the nucleus.

What do you get chromosomes from?

you have 2 sets of chromosomes and you get one set from your mother and one from you father. they're made of nucleic acids

What does your chromosome do?

Chromosomes carry genes (genes are short lengths of chromosomes) there are 23 pairs of chromosomes and they each contain alleles (different copies of the same gene) in the same place on each chromomsome.

What is chromosome'?

In the nucleus of each cell, the DNA molecule is packaged intothread-like structures called chromosomes.

Where are your chromosomes?

Chromosomes are located in the nuclei (singlular form: nucleus) of each cell in your body.

Why do you have chromosomes?

To store genetic information. Each cell in our bodies has over six feet of DNA. If that was all crumpled up and thrown in the cell, it would create a jumbled mess. Chromosomes contain spirals of compacted DNA neatly packaged and easily accessible by the cell. When a specific piece of data is needed ( Full Answer )

How many chromosomes does each new cell contain after mitosis if the the original cell had 52 original cell chromosomes?

They would each have 52. When a cell divides through mitosis, it copies the original chromosomes, pulls them apart so that there is a copy of the same set of chromosomes on each side of the cell, then divides. The original set of chromosomes will always be the exact same set as the daughter cell's s ( Full Answer )

Where do you get chromosomes from?

Chromosomes are inherited from parents - in sexually reproducing organisms, such as humans - half of the chromosomes come from each parent. You get chromosomes from nucleus of the cell.

How does the number of chromosomes in the two new cells of mitosis compare with the number in the original cell at the end of cell division?

They have exactly the same number of chromosomes. That is what Mitosis does- it creates two genetically identical cells. The tricky part in understanding Mitosis is that each of the CHROMOSOMES in the new cells will only have one CHROMATID. Prior to the completion of Mitosis, each of the chromoso ( Full Answer )

How many chromosomes does each daughter cell contain after mitosis if the parent cell had 52 original chromsomes?

Each daughter cells will contain 52 chromosomes after mitosis. After the replication during mitosis, the chormosomes become 104 (52x2). Later, they divide into two cells which splits the origainal 104 chromosomes into two (104/2) giving us 52 chromosomes as the final answer. If the parent cells ( Full Answer )

What might happen to a new cell if it didn't have the same amount of chromosomes as the original cell?

There are checkpoints during the cell's replication cycle which prevent a cell with aneuploidy (a different number of chromosomes). The spindel assembly checkpoint during metaphase of the cell cycle is important for checking for aneuploidy in cells. At his stage the sister chromosomes atta ( Full Answer )

What is a chromosome-?

Chromosome is having more than one X gene. Having more than one Xchromosome cause down syndrome.
